New inhibitors of rabbit muscle triose-phosphate isomerase
摘要:
We describe the synthesis and evaluation of three new competitive inhibitors of triose-phosphate isomerase. One of them (phosphoglycoloamidoxime: K-i = 4.5 mu M) is among the best reversible inhibitors so far reported for this enzyme. (c) 2005 Elsevier Ltd. All rights reserved.
Isoprenoid Biosynthesis via the Methylerythritol Phosphate Pathway: Structural Variations around Phosphonate Anchor and Spacer of Fosmidomycin, a Potent Inhibitor of Deoxyxylulose Phosphate Reductoisomerase
Fosmidomycin and its analogue FR-900098 are potent inhibitors of 1-deoxy-d-xylulose 5-phosphate reducto-isomerase (DXR), the second enzyme of the MEP pathway for the biosynthesis of isoprenoids. This paper describes the synthesis of analogues of the two reverse phosphonohydroxamic acids 3 and 4, in which the length of the carbon spacer is modified, the N-methyl group of 3 is replaced by an ethyl group
e and phosphonate derivatives were synthesized bearing a N-sulfonyl hydroxamate moiety. The phosphate derivatives represent competitive inhibitors for the class II-FBP aldolase catalyzed reaction, while the phosphonate isosteres are comparatively weaker inhibitors.
